Research On Security Strategy Of Wban Data

With the rapid development of wireless network technology,communication technology,hardware design technology and sensor technology,Internet of Things technology has become more and more popular.As an important branch of personal signs information monitoring,WBAN has the important research significance and broad application prospect in the era of China’s aging population.WBAN technology has been applied to many fields,such as telemedicine and monitoring,somatosensory games,tracking and positioning,intelligent home systems and so on.A WBAN is a kind of network information system consisting of various sensors,intelligent mobile devices(such as smart phones,PDAs),remote information centers,and various terminals that can display information,and the sensors are arranged on the human body surface or embedded in the human body.In this kind of systems,the sensors are mainly responsible for collecting relevant vital signs information or human-related environmental data,etc.The sensors either store the information directly in the local system or send them to the remote information processing service system through the wireless local area network,local base station,or intelligent mobile devices.Smart mobile devices can forward information to remote information systems as needed.In addition,the remote information service system can store and process the collected information and push the processed result of the information to various terminals which can display information,such as smart mobile terminal and real-time electronic information display systems.WBAN involves many aspects of technology,such as wireless communication technology,wireless network technology,distributed computing technology,hardware design technology,data fusion technology and so on.In order to standardize the wireless network system and standardize the research of the wireless body area network,the IEEE working group developed the standard 802.15.6 for WBAN in Dec 2011,and a lot of research results of WBAN have been made in recent years.On the other hand,the wireless body area network system mainly collects the personal information of the user,as a result,it may compromise the user’s privacy.In the open WBAN,the data collected by the wireless sensor nodes is easy to be eavesdropped or tampered maliciously.The nodes collecting information in the WBAN systems have the characteristics of relatively low computing power,limited storage space and limited energy.Moreover,as the human body’s posture will continue to change,the relative position of the nodes in the WBAN will change frequently,as a result,the structure of the WBAN system will change frequently,so,many security technologies can be applied to the ordinary Internet cannot be directly applied to the WBAN systems,and it is necessary to design security solutions for WBAN systems particularly.This paper mainly analyzes the structure and characteristics of the WBAN systems and summarizes the security research results in the WBAN,combining the security goals of the WBAN,this paper proposed a security scheme based on stochastic factors.Firstly,the characteristics and the structure of the WBAN are analyzed.Possible attack methods and security threats are analyzed based on the structure of the WBAN.Then,the research results are summarized for each stage of the work process of WBAN.The data acquisition phase,the data transmission phase,the data aggregation phase,the data storage phase and the data access phase of the WBAN are analyzed and compared respectively from the perspective of the WBAN’s security technologies.Then,see from confidentiality as well as reliability,according to the security requirements of WBAN,a security solution based on stochastic factor is proposed,which is based on the IEEE 802.15.6 standard.The scheme considers the communication protocols which are working for the remote information systems,the smart mobile devices,and the wireless sensor nodes.Then the attacker model is established,and the security of the scheme is analyzed from the attacker’s point of view.Then,the arduino development board and the temperature sensor are used to simulate the experiment,and the experimental results are analyzed.Finally,the content of this paper is summarized,and the development prospect and trend of WBAN are forecasted.
